Description
The SKY13408-465LF is a GaAs pHEMT Single-Pole, Triple-Throw
(SP3T) high power switch with 50 Ω terminated outputs. The high
linearity performance and low insertion loss achieved by the
SKY13408-465LF make it an ideal choice for 802.11a/c, WiMAX,
and higher power WLAN applications such as access points.
The switch is manufactured in a compact, 2 x 2 mm, 12-pin Quad
Flat No-Lead (QFN) package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
Functional Description
Electrical and Mechanical Specifications
Switching is controlled by three control voltage inputs, V1, V2, and
V3 (pins 9, 6, and 1, respectively). Depending on the logic voltage
level applied to the control pins, the RFC pin is connected to one
of the three switched RF outputs (RF1, RF2, or RF3) using a low
insertion loss path, while the paths between the RFC pin and the
other RF pins are in a high isolation state.
The absolute maximum ratings of the SKY13408-465LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
DC blocking capacitors are required on all RF ports of the switch.
The value of the capacitors determines the low frequency
operation. The isolated RF output ports are internally teminated to
50 Ω. The return loss in the isolation state is limited by on-chip
capacitors.
Typical performance characteristics of the SKY13408-465LF are
illustrated in Figures 3 through 6.
The state of the SKY13408-465LF is determined by the logic
provided in Table 4.
